Nanoparticles can travel from lungs to blood, possibly explaining risks to heart

Tiny particles in air pollution have been associated with cardiovascular disease, which can lead to premature death. But how particles inhaled into the lungs can affect blood vessels and the heart has remained a mystery. Now, scientists have found evidence in human and animal studies that inhaled nanoparticles can travel from the lungs into the bloodstream, potentially explaining the link between air pollution and cardiovascular disease. Their results appear in the journal ACS Nano.

Researchers build a single-molecule diode

Researchers of the University of Barcelona have led a project to create a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction while blocking the current in the opposite direction.

Nanodiamond-enhanced MRI offers greater range of diagnostic and therapeutic applications

Nanodiamonds - synthetic industrial diamonds only a few nanometers in size - have recently attracted considerable attention because of the potential they offer for the targeted delivery of vaccines and cancer drugs and for other uses. Thus far, options for imaging nanodiamonds have been limited. Now a team of investigators based at the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital has devised a means of tracking nanodiamonds noninvasively with magnetic resonance imaging (MRI), opening up a host of new applications. They report their findings today in the online journal Nature Communications.

Nano-notch sends self-assembling polymers into a spiral

A simple circular or hexagonal pit written into silicon can be used to generate self-assembling polymer spirals thanks to the addition of a tiny notch in the template, report scientists in the launch issue of Nano Futures.

Nanoparticle vaccine shows potential as immunotherapy to fight multiple cancer types

Researchers from UT Southwestern Medical Center have developed a first-of-its-kind nanoparticle vaccine immunotherapy that targets several different cancer types.

Self-assembled nanostructures can be selectively controlled

Plasmonic nanoparticles exhibit properties based on their geometries and relative positions. Researchers have now developed an easy way to manipulate the optical properties of plasmonic nanostructures that strongly depend on their spatial arrangement.

Freezing lithium batteries may make them safer and bendable

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage. The study is published online April 24 in Nano Letters.

Graphene holds up under high pressure

A single sheet of graphene, comprising an atom-thin lattice of carbon, may seem rather fragile. But engineers at MIT have found that the ultrathin material is exceptionally sturdy, remaining intact under applied pressures of at least 100 bars. That's equivalent to about 20 times the pressure produced by a typical kitchen faucet.

Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

Controlling electrons in graphene opens a new path to potential electronic devices

For the first time, scientists created a tunable artificial atom in graphene. They demonstrated that a vacancy in graphene can be charged in a controllable way such that electrons can be localized to mimic the electron orbitals of an artificial atom. Importantly, the trapping mechanism is reversible (turned on and off) and the energy levels can be tuned.

3-D models of multilayered structures on engineering scale from nanoscale damage profiles

Computer modelling of nano-indentation studies performed on ion-irradiated steels has generated 3-D stress-field maps on an engineering scale that agree well with experimental results.

Graphene 'copy machine' may produce cheap semiconductor wafers

In 2016, annual global semiconductor sales reached their highest-ever point, at $339 billion worldwide. In that same year, the semiconductor industry spent about $7.2 billion worldwide on wafers that serve as the substrates for microelectronics components, which can be turned into transistors, light-emitting diodes, and other electronic and photonic devices.

Graphene and gold make a better brain probe

A team from Korea created more flexible neural electrodes that minimize tissue damage and still transmit clear brain signals.

A new method developed for measuring carbon nanotubes

With this method can be measured e.g. the number of single walled carbon nanotubes and their concentration in a carbon nanotube layer.

Nanoparticles remain unpredictable

The way that nanoparticles behave in the environment is extremely complex. There is currently a lack of systematic experimental data to help understand them comprehensively, as ETH environmental scientists have shown in a large overview study. A more standardised approach would help to advance the research field.

New technique colors biomolecules in tissue

An extra detector on an electron microscope can help determine which molecules are found in which parts of a cell. This is what scientists at the UMCG and Delft University of Technology report in an article published today in the journal Scientific Reports. "This detector enables us to assign a colour to molecules in a cell," says Ben Giepmans, the team leader from Groningen. "Multicolour electron microscopes are a new addition to medical research, and they could generate interesting results."
